ccache: updated to 3.7.5

3.7.5:
New features
Added support for -MF=arg (with an extra equal sign) as understood by EDG-based \ 
compilers.

Bug fixes
Fixed a regression in 3.7.2 that could result in a warning message instead of an \ 
error in an edge case related to usage of “-Werror”.
An implicit -MQ is now passed to the preprocessor only if the object file \ 
extension is non-standard. This will make it easier to use EDG-based compilers \ 
(e.g. GHS) which don’t understand -MQ. (This is a bug fix of the corresponding \ 
improvement implemented in ccache 3.4.)
ccache now falls back to running the real compiler instead of failing fataly if \ 
an internal temporary file is missing after compilation.
Fixed a crash if localtime returns null pointer in localtime_r replacement.
Fixed header file dependency tracking when building ccache itself.
Fixed warning during configure in out-of-tree build in developer mode.
